本考案は、複数個の円盤刃体をその刃体量大々に筒状ス
ペーサを介在させた状態で回転軸芯方向に並設して構成
した茎稈切断用回転体の一対を、はぼ平行に配設した茎
稈細断装置に関する。[Detailed description of the invention] The present invention is a rotary machine for cutting stem culms, which is constructed by arranging a plurality of disc blades in parallel in the direction of the rotational axis with a cylindrical spacer interposed between the blades. This invention relates to a stem culm shredding device in which a pair of bodies are arranged approximately parallel to each other.
従来、この種の茎稈細断装置として、特開昭52−11
4199−W公報に、受刃をもつ高速回転体と低速回転
体を並設して互に反転回転させ低速回転体の複数の受刃
の間に全幅もしくは略全幅に亘って前記受刃の外径に近
い大径部材を固着し、かつ、この大径部材の外周部に、
低速回転体軸芯方向に平行な多数の稈穀係止用の凹凸条
を形威しである構成のものが開示されている。Conventionally, as this type of stem culm shredding device, Japanese Patent Application Laid-Open No. 52-11
Publication No. 4199-W discloses that a high-speed rotating body and a low-speed rotating body having receiving blades are arranged side by side and are rotated in reverse to each other, so that the outer side of the receiving blades is spread over the entire width or almost the entire width between the plurality of receiving blades of the low-speed rotating body. A large diameter member close to the diameter is fixed, and on the outer periphery of this large diameter member,
A configuration is disclosed in which a large number of concavo-convex strips for locking culms are formed parallel to the axial direction of the low-speed rotating body.
このものは、受刃上に供給された茎稈の姿勢が多少傾斜
していても、茎稈が大径部材の接当により、受刃の間か
らすり抜けたり、または傾斜が更に大になるのを防止で
き、茎稈抜は落ちのない良好な細断作業を行ない得るが
、高速回転体と低速回転体の回転によって茎稈を受取る
時、低速回転体に設けた凸条性の大径部材の外径は受刃
の外径と同寸程度の小さいものであるので、回転作用、
特に高速回転体の回転作用によって、茎稈が跳返される
故、両回転体間に良好に持込まれなく、また跳返された
茎稈が構成部材に巻付く欠点があった。Even if the posture of the stem culm supplied onto the receiving blade is slightly inclined, the stem culm may slip through between the receiving blades due to contact with the large diameter member, or the inclination may become even greater. However, when the stem culm is received by the rotation of the high-speed rotating body and the low-speed rotating body, the convex large-diameter member provided on the low-speed rotating body The outer diameter of the blade is small, about the same size as the outer diameter of the receiving blade, so rotational action,
In particular, because the stem culm is thrown back by the rotating action of the high-speed rotating body, it is not carried well between the two rotating bodies, and there is a drawback that the thrown back stem culm winds around the component.
本考案が解決しようとする技術的課題は、簡単な改良に
よって、両回転体の間に茎稈を確実に持込ませ、かつ、
その間をすり抜けさせない円滑確実な茎稈供給ができる
ようにする点にある。The technical problem to be solved by the present invention is to ensure that the stem culm is brought between both rotating bodies by simple improvement, and
The purpose is to enable smooth and reliable supply of stems and culms without allowing them to slip through the gaps.
上記技術的課題を解決するために講じた技術的手段は、
両回転体夫々に円盤刃体の間に介在させた筒状スペーサ
のうち他方の茎稈切断用回転体の円盤刃体間に対向する
ものの外周面に、回転軸芯方向はぼ全長にわたる茎稈掻
込み用突条を、他方の円盤刃体よりも突出させた状態で
設けるものである。The technical measures taken to solve the above technical problems are:
Among the cylindrical spacers interposed between the disc blades of each of the two rotary bodies, a stem culm extending over almost the entire length in the direction of the rotational axis is placed on the outer peripheral surface of the spacer that faces between the disc blades of the other rotary body for cutting culms. The raking protrusion is provided in a state that it projects more than the other disc blade.
上記技術的手段は次のように作用する。The above technical means works as follows.
両回転体に介在させた筒状スペーサのうち、一方のスペ
ーサにほぼ全長にわたる突条を他方の円盤刃体よりも突
出させた状態で設けであるから、両回転体の回転に伴っ
て供給される茎稈を受取る時に、はぼ全長にわたる突条
の存在故に、茎稈が必ず突条に接当して茎稈が円盤刃体
の間からすり抜けたり、または傾斜が大きく変ることは
ない。Of the cylindrical spacers interposed between both rotating bodies, one spacer is provided with a protrusion that extends almost the entire length and protrudes beyond the other disk blade, so that the spacer is supplied as the two rotating bodies rotate. When receiving a stem culm, due to the presence of the protrusion along the entire length of the handle, the stem culm will always come into contact with the protrusion, and the stem culm will not slip between the disc blades or the inclination will not change significantly.
また、前記突条を他方の円盤刃体より突設しであるから
、両回転体の回転作用を受けた茎稈が跳返されることな
く両回転体の間に良好に持込まれる。Further, since the protruding ridge is provided so as to protrude from the other disc blade body, the stem culm that has been subjected to the rotational action of the two rotating bodies can be carried well between the two rotating bodies without being bounced back.
本考案は、上記の結果スペーサに簡単な改良を行うだけ
で、次の効果を奏する。The present invention achieves the following effects by simply making improvements to the above-mentioned spacer.
すなわち、はぼ全長にわたる突条による茎稈のすり抜け
または大きな傾斜変更の防止の作用と、突条を他方の円
盤刃体より突設したことによる茎稈の跳返りのない良好
な持込み作用の相乗作用により、両回転体の間に茎稈を
確実に持込ませ、かつ、すり抜けさせない円滑な茎稈供
給ができるに至った。In other words, there is a synergy between the effect of preventing the stem culm from slipping through or large changes in inclination due to the protrusion extending over the entire length of the stalk, and the good effect of bringing the stem culm in without rebounding due to the protrusion being provided protruding from the other disc blade. As a result, the stem culm can be reliably brought between the two rotating bodies, and the stem culm can be smoothly supplied without slipping through.
従って、跳返された茎稈が構成部材に巻付くことに起因
する機能不良や危険状態を招くことなく、細断作業を能
率良く行わせられるようになった。Therefore, the shredding work can be carried out efficiently without causing malfunctions or dangerous situations caused by the rebounded stem culms wrapping around the structural members.
次に、本考案の実施例を図面に基いて説明する。Next, embodiments of the present invention will be described based on the drawings.

The ridge 13, which is integrally molded at three locations in the circumferential direction and rotates integrally with the spacer 12, allows the stem culm to be caught between the two rotating bodies 5.6, and the ridge 1 of the stem culm is
This is so that winding around No. 3 is less likely to occur due to its width.
